Hidden fender mounts
Discreet mounts accommodate full-coverage fenders for added utility.
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tire pressure for increased traction and comfort without the threat of pinch flats.
Tough Bontrager Hard-Case tires help keep flats from slowing you down.
DuoTrap S compatible
DuoTrap S integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.
IsoZone handlebar and grips
Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.
Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
